QuestionQ21

Routing Policy and Firewall Filters

Which two of the following statements are examples of exception traffic?

Choose two
  • A An IP packet with the Router Alert option set in the IP options field.
  • B SSH traffic to the local Junos OS device.
  • C An IP packet that has the IP precedence CoS bits of 111 in the ToS field.
  • D SSH traffic to a remote server on the Internet.
Explanation

Packets carrying the IP Router Alert option require routers along the path to examine them specially. SSH traffic destined to the local Junos OS device is a local packet processed by the Routing Engine. An IP precedence value is only a class-of-service marking, while SSH traffic to a remote Internet server is normally forwarded as transit traffic. Juniper documents that local packets include IP services such as SSH and are handled by the Routing Engine.
